colinneagle writes: A gear logo proposed to represent and easily identify open-source hardware has caught the eyes of the The Open Source Initiative, which believes the logo infringes its trademark.

The gear logo is backed by the Open Source Hardware Association (OSHWA), which was formally established earlier this year to promote hardware innovation and unite the fragmented community of hackers and do-it-yourselfers. The gear mark is now being increasingly used on boards and circuits to indicate that the hardware is open-source and designs can be openly shared and modified.

OSI has now informed OSHWA, which is acting on behalf of the open-source hardware community, that the logo infringes on its trademark. The issue at stake is a keyhole at the bottom of the open-source hardware logo, which resembles a keyhole at the bottom of the OSI logo. The gear logo was created as part of the contest hosted by the group that founded OSHWA, and the mark was released by its designer under a Creative Commons license, opening it up for the community to use on hardware.
